Pg-1230 Nx Eagle 12-Speed Cassette

Works great, good deal

This is the second SRAM rear cassette I've installed on my ebike. My first NX Eagle chain/cassette combo I left the chain on for way too long (2,500 miles) and over-stretched it and accidentally wore out my rear cassette too. Costly mistake! I first just attempted to replace my chain to fix some minor skipping but without replacing the rear cassette too the problem just got 100x worse. I rode around for 2 days not allowing my bike to shift into the my slipping gears and ordered this replacement right away. Once this was replaced, along with the chain, my ebike rode like new again. Moral of the story, this is a great product and works well on an ebike. However, I'd highly recommend getting a Park Tool CC-2 to keep a close eye on chain stretch, replace the chain @ .5 to avoid also wearing out your rear cassette and other drive train components. Due to high stresses applied from an ebike motor onto a drive train, via the chain, a new chain is recommended roughly every 1000 miles.

Muy buena y económica

For the price this cassette is awesome, and along with the SRAM GX Eagle shifter and derailleur breathed new life into my 12 year old Santa Cruz Tallboy. Decent shifts, even under load.

No complaints. They do the job. Check your hub type before ordering. Good value for money.

AS DISCRIBED

I had no issues with a direct replacement of the factory cassette of my 2019 Scott Genius. The fact that I needed to replace it in the first place is the reason for the 4 stars. The compromise between weight-saving and strength went a little too far into weight-saving in my opinion. When I caught a branch while pedaling along on a single track trail, it bent 2 cogs and literally tore the metal apart on one, so it was not repairable. I decided to replace the cassette with the Eagle GX, which is stronger, quite a bit more expensive, and also not compatible (XD driver!), which nobody told me. I learned a bit about hubs in the process, so no harm done. Trying to find an XD driver for my wheels turned out to be impossible, so I upgraded the whole wheel set and went fully carbon, converted the stock wheels to studs and bought this replacement.

I bought the entire GX groupset minus the cassette individually, because I wanted use an NX cassette so I didn't have to replace my hub to XD. Installed all the components and everything works superbly. I had no install issues because I did the necessary research and measurements. You should know your bottom bracket type and measurements, if you are boost or non-boost, which spacers you use and where (all information is available at SRAM) take a digital caliper and measure. Just make sure you watch the videos how to install these products before you purchase the components and try to install the wrong one. Be sure you have a new high quality derailleur hanger. This is not a first time beginner undertaking. Know when you have no idea and ask someone and if you don't know or don't have the right tools, take it to a bike shop. You will need a chain whip, and the right socket and tools to remove your existing cassette, and bottom bracket, and same for installing your bottom bracket. I used an SRAM DUB BSA boost+ bottom bracket 68/72mm. I lucked out because it had the correct spacer for the right side, plus the boost spacer I didn't need.

Ottima qualità

As described. Used for second set of wheels with Gx system.

Parfait

Moja kolejna kaseta do e-mtb. Solidna, w bardzo dobrej cenie. Prze dobrym traktowaniu i regularnej wymianie lancucha posłuży 2-3 sezony spokojne.

Denna kassett gör det den ska. Med kedja av GX kvalitet eller högre så sker växlingar bra.
